I am a professor in the Department of Computer Science at the University of California at Davis. I am one of the co-directors of the Computer Security Laboratory here.
I do research in computer security. Currently, my interests seem to focus on election processes, data sanitization, and the insider problem. I also like teaching.

I grew up in San Francisco. Here’s a picture of me in Coit Tower, looking at a kiosk describing the life of Lillian Hitchcock Coit, whose estate funded the building of Coit Tower. It’s on the ground floor. If you go there, take the elevator and walk up the stairs to the top. You will get a fabulous view of the City!

Graduate Admissions. Click here for information on being admitted to do graduate work in information assurance or computer security, including a link to the on-line application. Please do not write me asking about your chances of getting in, or if I will admit you. I get too many such letters to answer them, and my answers are the same for everyone: I don’t know, and I do not have the authority to, respectively.

There once was an old man from Esser,
Whose knowledge grew lesser and lesser.
It at last grew so small,
He knew nothing at all,
And now he’s a college professor.
